The actress starred as the only girl in the quadruplet-centered Nicky, Ricky, Dicky, & Dawn, and over the weekend, shared some sweet words to fans, the network and to Dawn, who she’s played on screen for the last for seasons.

“I have grown up as Dawn, for 4 years I have had the honor of playing such an awesome part,” she wrote. “Dawn is strong, confident, funny and so much more.”

Lizzy added, “Than you so much Nickelodeon for taking a small town girl, and believing in her. I am so grateful and blessed to have spent the last 4 years of my life on such an amazing show.”

While Lizzy doesn’t say this is the end, end, it’s looking that it might be.
